COMBINED CALENDAR CALCULATOR AND CHARTQ- q Application filed. February 6, 1924. Serial No.'691,005..

Th s invention relates to a COIIlblDBdOalendar calculator audchart and is more particularly adapted for use in connect1on w1tl 1 an, incubator for hatching-eggs,

a ,;The primary object. ofthe present l endar calculator byaneansof which the rotatable discs are frjictionallyisecured against j t n:.' {.'li.tfll i.-.'.- 1. '1

; These and other objects are accomplished by providing a. construction and an arrange- 2n ment ofjhe various parts in the manner rei a b des ib di a d -rer rl l'y pane to the master disc by aneyelet'rivet 24.

ed Q t t e.appe e ms-eWe Referring;to the drawings, Fig. 1 is a top plan view sl o wing the preferred;.e'mbodi ment of my improvedicalendar calculator, Fig. 2is a cross secti onal view taken on the vertical planeipassing through the lon-,

gitudinal axis of the-calendar, calculator in Fig. 1. ,v

-Fig, 3 is a topplan View showing the construction of one of the rotatable dises, and

Fig. 4 -is a .top plan View of one of the strips which are positioned between the rotatable discs for frictionally securing them against rotation.

In carrying out my invention I have provided a novel form of master or stationary disc 10, which has formed integrally therewith an "upwardly extending portion 11, which forms a support or handle. In order to reinforce and strengthen this handle portion I have provided an.extension thereof which is formed integrally with the portion 11, and folded back asshown at 12 to forn'r a reinforcing member 13 secured to rear side of the calendar calculator. the master disc 10 and the reinforced portion 13 is rotatably mounted a plurality of discs hereinafter described. The master disc 10 has printed on a sector 14 thereof the twelve calendar months of the year arranged in the are of a circle as shown at 15. Arranged consecutively around the remaining are of the circle are the numerals l to 21 inclusive, which denote the length of time the calendar-calculator Between normally -r equired for hatching a setting of eggs. The master disc .is provided witha Izldlfil'llllfi 10 with the words ..Date set indicating the day on which the eggs were placed intheincubator. The radial line 17 on the master-dismpoints to'the indication of the expiration of the twenty-one days or the time necessary for normally hatching a setting of eggs, Pivotedconcentrically with the master disc is an indicator 18 which is adapted to be adjusted to indicate the calendar month in wl icl:1;the. incubator is set.

Another pimportant feature 'of my 7 improved calendar calculator. is the provision of means for reinforcing and frictionally securing the rotatable. calendar discs in their positions to, which theyare adjusted. This mechanism comprises a plurality of strips 9 which are positioned between the rotatable discs 20,21,22 and 23., The discs 20, 21, 22 and 23 are,pivoted eoncentrically Each of the; strips 19. as well as a supplemental strip 25is securedin place between the rotatable, discs by, the eyelet rivet 24 as clearly shown in Figs. l and 2. The upper ends of the =strips19 are secured to the handle portions ll and -l 3 ofthe master disc 10 by asecondeyelet rivet 26. It Will of course be understood that these strips are preferably made of paper but might well be made of brass, aluminum or celluloid. It will alsobe seen fromthe above description thateach of the discsQO, 21, 22 and 23 are separated from each other by the strips 19 in such a manner that the strips offer a frictional resistance to the rotation of each of the discs and thereby frictionally lock each of these discs in the position to which theyare adjusted so that each disc may be individually adjusted withoutafl'ecting the adjustment of any of the other .discs. The supplemental strip 25 is secured in position by the eyelet rivets 24: and 26 and extends upwardly between the handle portions 11 and 13' of the master disc 10 to the top portion thereof and secured in position by an additional eyelet rivet 27, and-thereby furtherreinforcing thehandle portion of the calendar calculator.

Another important feature. of my im proved calendar calculator isthe provision of a novel construction. of a rotatable disc which permits the easy adjustment of these discs about their common pivots. This coneggs.

struction comprises the bevelling or tapering of the discs :as shown at 28 of that por tion of the disc 'whichextends outwardly on the periphery thereof as shown at 29, and carries the calendar days of the month. This bevelled or tapered portion 28 of each of the rotatable discs 20, 21, 22 and 23 is arranged so that when the discs are-rotated between the frictional strips 19 they will be easily guided through'without tearing' or straining the discs unnecessarily and thereby prolong the life of the calendarca lculator. The disc 20 carries on its outwardly projecting peripheral portion thereof the calendardays from 1 to 7 inclusive and the disc QI-carries the calendar days from "8 to Minclusive; 'lhe disc=22 carries the calendar days from '15 -'to 21 inclusiveand the disc 23 carries the calendardays from 22 to 31 inclusive. On the front face -0f-the='calendar calculator and'=pre'fer ably on the u'pper portion of the Fh-andle' 1 1d hsve 'pro as indicated in Fig. *1, the pointer o'r -indi-' cator 18*pointi'ng to July and 'the rotatable disc 20 is rotated until'thenumeral i regist-ers with the line 16 which is the date set. Then each of the discs 21, 22 and 23 is adjusted so that the calendar days are arranged in consecutive order and'when in this position the numeral 21 on the vradial line 17 will register with 25 ion the disc 23 indicating that-the setting '-of eggs will be hatched on the 25th day ofJuly. The mas ter 'disc of course is provided -with""instr.uc tions between=the first and the twenty-first, indicating the various operations necessary to obtain the best results from a setting of In the adjustment of the discs 20, 21, 22 and 23 it will readily beseen that the strips 19 'not only separate these discs but l'rietionally secure them against rotation' so that each of the discs may be adjusted independently of the other, andit will, of

course, be seen that by tapering or inclining that portion of each of the discs that carry the calendar dates the discs may readily'be rotated between the'strips with great facility.

\Vhile in the above specification I have described one embodiment which'my invention may assume in practice, it'will of course be understood that the same is capable of modification and that modification may be made without departing from the spirit and scope of the invention as expressed in the following claims.
